I want to modelise an heat-pump on Simscape, using the geometric approach of the heat-exchanger (using System-level Heat-Exchanger so). But in the heat-exchanger block, regardless of whether we work with a two-phase fluid, a thermal fluid or moist air, it seems that we can only model exchangers with tubes and fins.
Someone know if it is possible to model a brazed plate heat exchanger on Simscape ?
Thank you.

I would recommend the following combination of options:
The key is to choose "generic" for tube section, so you can set the heat transfer area by the section area and perimeter, and to choose Colburn equation for heat transfer correlation. You may adjust the coefficients, depending on what kind of data you have, to match the heat transfer performance.

is "Total length of each tube" consider to be length plate to ?

it's the length in the direction of the flow; usually it's indeed the length of the plate.
